Abstract: The present invention relates to a portable electronic device comprising: a housing; a camera unit, which can be rotated relative to the housing, for capturing an image; magnetic detection means for detecting a rotational position of the camera unit; image processing means for modifying the image captured by the camera unit depending on the rotational position detected by the magnetic means. The magnetic detection means comprise a magnetic transmitter attached to the camera unit and a magnetic receiver attached to the housing.

Abstract: The invention discloses a device for realizing a power supply contact between printed circuits on a printed circuit board and a current source. The device includes a casing and an electronic board which has a metallic surface connected to a power supply contact, on the one hand, and to circuits to be supplied with electric power on the other. The printed circuit board is kept on the casing by at least one securing means secured to the printed circuit board on the metallic surface and secured to the casing on a securing surface. The securing means has a conducting part between the power supply contact and the metallic surface for leading the power from the power supply contact to the circuits to be supplied with power.
